How do I enable CDC hosting and tear down track/lock datasets?

Set ol.cdc.enabled=true plus CoreIQ URL and service token. GET /cdc/status and POST /cdc/teardown require RACF Basic. Teardown deletes *.CDC.TRACK / *.CDC.LOCK under the caller’s RACF identity and is idempotent; it never deletes the shared status KSDS. This is the gateway CDC hosting path, not BMC AMI IAM file-type CDC.
